About Surge Protectors

Surge Protection Devices (SPDs) are designed to protect electrical equipment from voltage spikes. These devices can be used in both residential and commercial settings to prevent damage from power surges, lightning strikes, and other unexpected power issues. They are available in a variety of sizes, shapes, and configurations to meet the needs of any application.

Types of Surge Protection Devices

Different types of SPDs are available for different applications. Service entrance surge protectors are typically installed at the point where power enters a home or building. Shop surge protectors provide protection for tools and other electrical equipment used in workshops or factories. Surge suppression devices are designed to detect and respond quickly to sudden changes in voltage levels while surge suppressors provide long-term protection against damaging voltage spikes.

How Surge Protection Devices Are Made

SPDs are made with a combination of materials including copper wiring, capacitors, resistors, inductors, MOVs (metal oxide varistors), fuses, diodes and circuit boards. Each component is carefully chosen based on its ability to effectively absorb energy from high-voltage transients without causing damage.

Industries that Use Surge Protection Devices

Electricians, engineers, IT professionals and other industry professionals use SPDs as part of their job duties. Electricians use them when wiring homes or buildings while engineers use them when designing electrical systems for large industrial facilities. IT professionals use them when setting up computer networks while facility managers rely on them to keep their buildings’ systems running smoothly.
